Abstract
AIM This study aimed to clarify tumour characteristics and treatment patterns for patients with colorectal cancer aged 80 years or older and the impact of age on survival using a large-scale cancer registry database. METHOD The database was used to identify 40 851 colorectal cancer patients who underwent surgery between 1995 and 2004. Patients were stratified into four age groups (< 50, 50-64, 65-79, ≥ 80 years). Demographics, tumour characteristics, treatment pattern and survival were compared between age groups. Additionally, the impact of lymph node dissection and adjuvant chemotherapy on survival was studied using the propensity score-matching method. RESULTS In the over 80 age group, patients were more commonly female, with right colon cancer, multiple primary cancers, history of colorectal cancer, high serum carcinoembryonic antigen values, large tumour, undifferentiated histology, and more frequent pT3/pT4 tumours. In contrast, metastatic disease, central lymph node dissection and adjuvant chemotherapy were less frequent. Overall survival and cancer-specific survival decreased with increasing age for any stage. Multivariate analysis showed age to be an independent predictor of overall survival (hazard ratio 1.45, 95% CI 1.34-1.58, P < 0.001). In the propensity score-matched cohort, overall survival of the patients with central node dissection and having adjuvant chemotherapy was significantly better than for those without. This difference was not statistically significant in patients aged 80 and above. CONCLUSION This study showed a significant difference in tumour characteristics and treatment patterns in patients aged 80 and above. Even after adjustment for clinicopathological factors, the difference in survival persisted and age was considered a robust prognostic factor.

Abstract
AIMS The aim of this study was to examine whether low serum potassium concentration could be a predictor of chronic kidney disease (CKD) in a community-based cohort. MATERIALS AND METHODS We enrolled 1001 subjects, median period of 5.7 years, and evaluated the risk factors for CKD, defined as estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m(2), and assessed whether low serum potassium concentration could predict CKD. RESULTS Compared with the subjects without development of CKD, age, body mass index, fasting plasma glucose, uric acid (UA), creatinine and serum sodium concentration were higher, and serum potassium concentration was lower in subjects with development of CKD. Univariate Cox regression analyses demonstrated that age, body mass index, fasting plasma glucose, UA, creatinine, serum sodium concentration and serum potassium concentration were associated with progression of CKD. Multiple Cox regression analysis revealed that age, gender, creatinine and serum potassium concentration were independent predictors of CKD after adjustment for covariates. When serum potassium concentration was below 4.0 mmol/l at baseline, hazard ratio (95% confidence interval) of developing CKD was 2.65 (2.04-3.44; p < 0.0001). CONCLUSIONS Serum potassium concentration could be a clinically relevant risk factor for the progression of CKD, defined as eGFR < 60 ml/min/1.73 m(2) , in healthy subjects.

Abstract
A five-step and scalable synthesis of racemic cytoxazone, a novel cytokine modulator, was accomplished in a total yield of 51% from p-methoxycinnamyl alcohol without any protective groups. The keystep was the new one-pot azidohydroxylation procedure by the combined use of NaN3-H2O2-CH3CN. The epoxidation of an olefin by means of an in situ-formed iminohydroperoxide worked well, accompanied by the concomitant regioselective ring opening reaction of the resulting highly reactive epoxide with an azide ion.

Abstract
A 59-year-old male patient presented with left chest discomfort on admission. His medical history included encephalitis in childhood and his smoking history was 20 cigarettes per day for 40 years. A physical examination showed an anemic and edematous face with weak respiratory sounds in the left lung. The patient had elevated calcium levels and decreased hemoglobin and potassium. His parathyroid hormone-related protein level was elevated. Thoracic radiography showed cardiomegaly and computed tomography revealed a left lung mass with invasion of the heart and pleural effusion. Magnetic resonance imaging showed endocardial invasion of the tumor mass. Gallium-68 imaging revealed positive accumulation in the region surrounding the heart. No diagnoses were possible upon frequent cytology of his sputum and pleural effusion. The patient died from congestive heart failure with anoxia 38 days after admission. An autopsy revealed tumoral mass occlusion in the left main bronchus and tumoral invasion of the left atrium, left ventricle, and aorta.

Abstract
A 94-year-old female patient presented with anorexia and left axillar lymphadenopathy on admission. Her past history was angina pectoris at 83 years of age and total gastrectomy due to gastric cancer at 87 years. The family history revealed that her son had had a malignant lymphoma, the histopathological diagnosis of which was diffuse large B-cell lymphoma. A physical examination showed both cervical, axillar, and inguinal lymphadenopathy without tenderness. She had elevated lactate dehydrogenase, ferritin, and soluble interleukin-2 receptor (sIL-2R). Whole-body computed tomography confirmed the cervical, axillary, and inguinal lymphadenopathy. Gallium-68 imaging revealed positive accumulation in these superficial lymph nodes. A right inguinal lymph node biopsy showed features of Epstein-Barr virus-associated lymphoproliferative disorder. Immunohistological studies on this lymph node biopsy showed CD20-positive large cells, CD3-positive small cells, and CD30-partly-positive large cells. In situ hybridization showed Epstein-Barr virus-positive, LMP-partly-positive, and EBNA2-negative cells. She refused chemotherapy as her son had died from hematemesis during chemotherapy. She received intravenous hyperalimentation for 1 month after admission. No palpable lymph nodes were identified by physical examination or computed tomography 3 months after admission, and regression of lactate dehydrogenase, ferritin, and sIL-2R was observed. She recovered from anorexia and was discharged. She died from pneumonia 10 months later after initial symptoms of anorexia. The autopsy showed no superficial lymphadenopathy.

Abstract
PURPOSE Recently, sclerotherapy using a new sclerosing agent (aluminum potassium sulfate and tannic acid) has become widespread in Japan as a treatment for hemorrhoids. In the present study, we investigated whether sclerotherapy or surgical therapy (hemorrhoidectomy) is superior in terms of the therapeutic outcomes at 4 years. METHODS We sent a questionnaire on symptoms and the degree of satisfaction to patients who underwent sclerotherapy or hemorrhoidectomy for grade 3 or 4 hemorrhoids in 2007, and compared the two therapies based on the responses, with respect to superiority of the therapeutic outcomes at 4 years. To identify the factors affecting the symptom-free and satisfaction rates, the univariate and multivariate analyses were performed for the following seven parameters: age, sex, degree of hemorrhoids, presence of external hemorrhoids, past history of treatment for hemorrhoids, number of hemorrhoids treated and the type of treatment. RESULTS Overall, 75 % of the patients (195/260) responded to the questionnaire. In this study, the symptom-free rates were 53 % (30/57 patients) in the sclerotherapy group and 80 % (111/138 patients) in the hemorrhoidectomy group, and the satisfaction rates were 70 % (40/57 patients) in the sclerotherapy group and 88 % (121/138 patients) in the hemorrhoidectomy group. The results revealed that the type of treatment was the only factor affecting these two outcomes. CONCLUSIONS Our results indicate that hemorrhoidectomy is superior to sclerotherapy. These findings may be useful in the treatment of hemorrhoid patients.

[PMID: 23598247 DOI: 10.1016/j.bmc.2013.03.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2013] [Revised: 03/11/2013] [Accepted: 03/15/2013] [Indexed: 01/26/2023]
Abstract
With the aim to address an undesired cardiac issue observed with our related compound in the recently disclosed novel series of renin inhibitors, further chemical modifications of this series were performed. Extensive structure-activity relationships studies as well as in vivo cardiac studies using the electrophysiology rat model led to the discovery of clinical candidate trans-adamantan-1-ol analogue 56 (DS-8108b) as a potent renin inhibitor with reduced potential cardiac risk. Oral administration of single doses of 3 and 10 mg/kg of 56 in cynomolgus monkeys pre-treated with furosemide led to significant reduction of mean arterial blood pressure for more than 12 h.

[PMID: 22804246 DOI: 10.2174/156652412802480844] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2011] [Revised: 02/20/2012] [Accepted: 02/21/2012] [Indexed: 12/11/2022]
Abstract
The p53 protein is a sequence-specific DNA-binding factor that regulates inflammatory genes such as CCL2/MCP-1 that may play a role in various diseases. A recent study has indicated that the knockdown of human p53 leads to a strong negative regulation of CCL2 induction. We are therefore interested in how p53 regulates CCL2 gene expression. In the following study, our findings indicate that UV-induced p53 accumulation in mouse macrophages significantly decreases LPS-induced CCL2 production, and that p53 binds to CCL2 5'UTR in the region (16-35). We also found that a p53 domain (p53pep170) mimics full length p53 to down-regulate CCL2 promoter activity. Treatment of p53-deficient mouse primary macrophages with synthetic p53pep170 was found to decrease LPS-induced production of CCL2 without association with cellular endogenous p53. CCL2 production induced by lentiCLG in human monocytes or mouse primary macrophages was blocked in the presence of p53pep170. Overall, these results demonstrate that p53 or its derived peptide (p53pep170) is an important regulator of CCL2 gene expression via its binding activity, and acts as a novel model for future studies linking p53 and its short peptide to pave the way to possible pharmaceutical intervention of CCL2-mediated inflammatory and cancer diseases.

Yamada K, Yamaguchi M, Asano M, Fujita S, Kobayashi R, Kasai K. Th17-cells in atopic dermatitis stimulate orthodontic root resorption. Oral Dis 2012; 19:683-93. [PMID: 23279451 DOI: 10.1111/odi.12053] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2012] [Revised: 10/15/2012] [Accepted: 11/25/2012] [Indexed: 12/19/2022]
Abstract
OBJECTIVE The aim of this study was to investigate how atopic dermatitis (AD) contributes to root resorption during orthodontic tooth movement. MATERIALS AND METHODS Atopic dermatitis model mice and wild-type mice were subjected to an excessive orthodontic force (OF) to induce movement of the upper first molars. The expression levels of the tartrate-resistant acid phosphatase (TRAP), IL-17, IL-6, and RANKL proteins were determined in the periodontal ligament (PDL) by an immunohistochemical analysis. Furthermore, the effects of the compression force on co-cultures of CD4(+) cells from AD patients or healthy individuals and human PDL cells were investigated with regard to the levels of secretion and mRNA expression of IL-17, IL-6, RANKL, and osteoprotegerin. RESULTS The immunoreactivities for TRAP, IL-17, IL-6, and RANKL in the AD group were found to be significantly increased. The double immunofluorescence analysis for IL-17/CD4 detected immunoreaction. The secretion of IL-17, IL-6, and RANKL, and the mRNA levels of IL-6 and RANKL in the AD patients were increased compared with those in healthy individuals. CONCLUSION Th17 cells may therefore be associated with the deterioration of root resorption of AD mice, and may explain why AD patients are more susceptible to root resorption than healthy individuals when an excessive OF is applied.
